First time he saw my pussy bit awkward 25F

About 2.5 weeks in we go on a road trip with some friends and we hit absolute gridlock moving a little every 5 mins after a car accident. I had just had a large coffee and lots of water so I had to pee very bad. Shoulder very exposed and shoulder full view other cars. Everyone knew I had to go bad for about 2 hours… finally couldn’t take it… BF had a large wide mouth hydro and I was gonna pee in it. Owner car very concerned about me missing… and he goea “it’s okay I’m gonna help squat in your seat.” So I was by by window him in middle I was wearing a skirt and as I’m squatted he sticks his head underneath pulls my panties to side and holds the bottle flush. He goes “okay let her rip its flush against you , you are good.” I then take a horribly embarissingly long loud pee into the hydro. When I was mid pee he goes wait slow it , getting close to top, he looks and goes still got space I was so fortunate I could then relieve my whole bladder and only had a little space left it was perfect size…. He then wiped me with his shirt sleeve…. He also was able to keep my pussy shielded from anyone else seeing the whole time.

Was so embarrassing but that was first time he saw my pussy.
